"The EPA says it studied the effect of waiving the requirement and believes it would have had little impact on corn prices"

Ron Paul has been saying for YEARS we needed to do away with the EPA and come up with an EFFECTIVE way to help the environment. Ethanol decreases our fuel economy which in turn makes us buy MORE FUEL and also increases the fuel tax revenue... Follow the MONEY. Wearing out injectors and engines prematurely also helps the auto industry. The fuel is "good enough" to keep the vehicle running past the warranty but not much further. Look for gas stations close to marinas as they don't put ethanol in boat fuels.

Ethenol is one of those things that sounds great in theory, but has proven to be harmful in practice.

Hydrogen fuel cell. Increased mpg, no exceptions for "light trucks", aka SUV's. Get on with the business of responsible action to limit our fuel consumption, no more ducking and running. The USA consumes 25% of the world's petrol and most of that is due to the car culture, mostly, SUVs.
